求教菜鸟问题:nbuf slength是什么意思
FUNCTION boolean GetComputerNameA(ref string cname,ref long nbuf)LIBRARY "Kernel32.dll" alias for "GetComputerNameA;Ansi"FUNCTION boolean GetUserNameA(ref string uname,ref ulong slength)LIBRARY "advapi32.dll" alias for "GetUserNameA;Ansi"
FUNCTION int GetSystemMetrics(int indexnum)LIBRARY "User32.dll"
我想求教nbuf slength indexnum分别是什么意思,他们的命名规则是什么,谢谢!
